THE BURMANNIACEA OF THE MALAY PENINUSLA. 335 
B. GRACILIS, n. sp. was discovered by Mr. CurTIs at Tintow 
in Kedah in 1889, and is apparently an undescribed species. 
Like B. tuderosa it is saprophytic and inhabits dense jungle. 
The whole plant is from six inches to a foot tall, with a 
slender branched stem, on which are a few narrow lanceolate 
scale-like leaves $ inch long. The inflorescence is a branched 
cyme, the branches of which are about ? of an inch long, the 
flowers few, seven or eight in number, w ake pedicelled. The 
pedicels a quarter of an inch long with lanceolate acute 
bracts nearly as long (about ? ofthe length). The perianth 
is a quarter of an inch long, olipcie in outline with distinct but 
not very large wings. The sepals are small, ovate, lanceolate ; 
the petals very much smaller, short and blunt. - The upper part 
of the connective of the anther is bilobed, the lobes denticulate 
rounded not very dissimilar to those of B. celestis, but rounder, 
the anther cells are prolonged into somewhat long points, 
and the central tooth does not descend below them. The 
style is long, the stigmas reniform, the ovary small, the seeds 
fusiform acute at both ends. 
GYMNOSIPHON is also a saprophytic genus, of which a consi- 
derable number of species are widely scattered over the 
tropical zones. In texture they are more like some of the 
Burmannias, being very fragile and delicate and not fleshy like 
Thismia. ‘The common species here, I thought at first, might be 
BLUME’S G. aphyllum, of which the description is too meagre 
really to distinguish it. But on examining the herbarium and 
library of Buitenzorg, where many of BLUME'S types are kept, 
I found a little rough sketch of BLUME’S plant signed by him- 
self, which is quite unlike our species. There was no specimen 
in the herbarium. BECCARI in “ Malesia” (i., p. 241,) described 
and figured G. dorneense from Borneo and ©. puspormpon: from 
New Guinea; BLUME’S G. aphy/lum comes from Java. Ac- 
cording to BLUME’s sketch it has two large bracts at the base 
of the flower, which does not occur in our species. I have 
little doubt that the latter is BECCARI’S G. borneense although 
that is represented as rather fleshier and thicker in the 
stem than the Straits plant.
